Patent EP-0280045-A1 (EP)
Inventor: HAYASHI MINORU
IPC: C06D5/00
Filed: 1988-01-25
Abstract: This invention concerns a gas generating apparatus for inflating an air bag whereby any shortfall in the quantity of gas required for inflating the air bag can be overcome by replenishing the air bag with air. If the gas generating apparatus is accordingly reduced in size and weight with a corresponding reduction in the quantity of gas generating agent used therein, the air bag is not inflated to a sufficient extent and its function as a safety apparatus in time of collision is thereby compromised owing to the reduction in the amount of gas generated. 
     This problem is solved by an air intake opening 2a₁ with a large diameter which is formed at the center of said housing body 1 along an axis thereof; a mixing chamber 4b which is disposed at the center of said housing body 1, connected to said air intake opening 2a₁ in alignment with said axis, and connected to open into said air bag; a combustion chamber 8 which is formed inside said housing body 1 on the inside of the outer periphery thereof and which generates a high-pressure gas upon combustion of a gas generating agent; and a multiplicity of nozzles 7 around the entire circumference of a junction portion between said air intake opening 2a₁ and said chamber 4b which eject said high-pressure gas from said combustion chamber 8 toward an opening of said mixing chamber 4b at high speed.

Abstract: The present specification discloses a cooker (1) with a hinged oven door (7). A control panel (13) incorporating control knobs (15) is located above the oven door (7) and these control knobs (15) can become heated to undesirable temperatures and form a depository form grease etc, due to the heated air flow passing thereover when the oven door (7) is open whilst the oven (5) or a grill (11) located therein, is in operation. 
     The present invention provides a vent (19) between the control panel (13) and the oven door (7), the vent (19) communicating with a source of air (21) which is cooler than the air issuing from the open door (5). This cooler air flow thus tends to cool and deflects the hot air flow from the oven (5) away from the control panel (13), thereby at least reducing the above problem.

Abstract: One of the reacting partners whose concentration does not substantially vary during the reaction is immobilized in the porous carrier phase. A solution of the other partners in a liquid is passed through the carrier whereby the reaction occurs and generates a signal which is picked up from the exhaust liquid. The magnitude of the signal depends on the rate of flow of the liquid through the carrier. This rate is kept under control and constitutes one of the parameters useful in measuring said reaction.
